David Ulevitch, General Partner at Andreessen Horowitz (a16z), who co-leads the firm’s American Dynamism practice with Katherine Boyle joins Sourcery to break down America’s comeback. With the encouragement of Marc Andreessen and Ben Horowitz, the $600M fund was founded around 2020 to invest in companies that support the national interest: aerospace, defense, public safety, education, housing, supply chain, industrials, and manufacturing.

David shares how American Dynamism evolved from a meme to a movement within a16z, inspired by Marc and Ben’s early conviction at Netscape that the next wave of great technology companies would serve the national interest.

From early investments like Anduril, Flock Safety, and Hadrian, to a16z’s growing policy arm in Washington D.C., David reveals how the firm is bridging the gap between Silicon Valley and the national mission, and why he believes private capital must lead the next American resurgence.

We discuss:

• ​The story behind American Dynamism’s rise
• ​The private capital boom powering national resilience
• ​JP Morgan’s $1.5T “Security & Resiliency” initiative
• ​AI’s role across defense, logistics, and manufacturing
• ​Why venture capital must “fund freedom like our lives depend on it.”

Key Points

• ​Why Marc & Ben backed David & Katherine for a national mission. American Dynamism was born from the belief that Silicon Valley’s greatest founders should again build for the public good, across defense, energy, manufacturing, & more.
• ​From meme to $600M fund. What began as a thesis between David Ulevitch and Katherine Boyle became a $600M dedicated fund and a defining pillar of a16z’s vision for national resilience.
• ​Private capital is America’s new resource. a16z’s model funds R&D independently while enabling the government to buy finished products, accelerating innovation & cutting red tape.
• ​AI is reshaping the foundations. From Anduril’s Eagle Eye headset to swarm drones and AI-powered logistics, technology is redefining how America powers, protects, and scales.
• ​The reindustrialization flywheel is spinning. With JP Morgan’s $1.5T initiative and growing investor conviction, national resilience is no longer niche, it’s a generational investment frontier.
